HP ProBook 4431s 笔记本键盘的拆卸

为了给HP ProBook 4431s笔记本清理灰尘，尝试拆卸键盘。将电池去掉反过来倒过

去看了N遍，硬是没找到下手的地。将电池盒后面的几颗螺丝卸掉后，尝试从前面撬开

键盘。键盘确实被撬开了一个拐角，然后就撬不动了，如果再横施暴力的话，恐怕这台

半新的机器要报废了。无奈只好放弃拆卸，可是想将键盘复原的时候，却发现无论如何

也不能将键盘弄服帖了，就是一角翘着，打字也不顺手了。

唉，这可这么好，好好一台机器被弄残了，得想办法给整回去。网上找寻一番，楞

是没找到这款机器的拆卸方法，最后还是在一个坛子里的回帖上看到可以到HP官网上

找资料。没想到官网上还真有键盘的拆卸方法。

这是原版英文说明：
